Maximum power transfer Solution

STEP 0: Pre-Calculation Summary
Formula Used
Maximum power = ((Thevenin's voltage^2)*Load resistance)/(Load resistance+Thevenin's resistance)^2
P = ((Vth^2)*RL)/(RL+RTH)^2
This formula uses 3 Variables
Variables Used
Thevenin's voltage - Thevenin's voltage defines the equivalent voltage using thenvenin's theorem. (Measured in Volt)
Load resistance - Load resistance defines the effective resistance at the load. (Measured in Ohm)
Thevenin's resistance - Thevenin's resistance is the resistance measured at terminals AB with all voltage sources replaced by short circuits and all current sources replaced by open circuits. (Measured in Ohm)
STEP 1: Convert Input(s) to Base Unit
Thevenin's voltage: 10 Volt --> 10 Volt No Conversion Required
Load resistance: 10 Ohm --> 10 Ohm No Conversion Required
Thevenin's resistance: 1.5 Ohm --> 1.5 Ohm No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
P = ((Vth^2)*RL)/(RL+RTH)^2 --> ((10^2)*10)/(10+1.5)^2
Evaluating ... ...
P = 7.56143667296786
STEP 3: Convert Result to Output's Unit
7.56143667296786 Watt --> No Conversion Required
FINAL ANSWER
7.56143667296786 Watt <-- Maximum power
